Milorganite 6-2-0 Professional Product Line

Milorganite Classic 50 lb bags

This is the product we have made for 90 years. It is the leading organic nitrogen fertilizer used. Across North America and around the world, anywhere you need to fertilize, Milorganite is the proven, reliable and safe organic nitrogen fertilizer. Sized at SGN 160, this fairway sized granule quickly drops through the turf canopy to rest on the soil surface until rain or irrigation activates its nutrients.

Milorganite Greens Grade 50 lb bags

The same nutrient package you get from the original Milorganite is now available in a Greens Grade. These SGN 90 granules contain the same nutrients as Milorganite Classic. The particles are small enough to fall into the canopy of close-cut turf. This minimizes mower pick-up and the impact on ball roll. Spoon-feeding greens with Milorganite Greens Grade keeps your golfers returning time after time!

Milorganite 1,000 lb and 2,000 lb bulk bags

Milorganite Classic and Milorganite Greens Grade is available in both 1,000 and 2,000 lb bulk bags. These large packs provide you with convenience and reduce packaging waste. These heavy-duty bulk bags are plastic lined to resist moisture, and durable lift straps for easy handling. The closeable spout simplifies filling spreaders.

Size Guide Number (SGN) and Uniformity Index (UI)

The Size Guide Number and Uniformity Index both accurately define the size of a fertilizer. SGN is the average millimeter (mm) diameter of that fertilizer. The Uniformity Index defines how much of that fertilizer actually meets these size requirements.

In other words, a high UI indicates a fertilizer that is very uniform. A low UI indicates that the granule size varies considerably. High UI fertilizers spread accurately and, if you are purchasing a blended fertilizer, indicate that the blend will tend to be uniform.
